The softmmu/ directory contains files specific to system
emulation. Rename it as system/. Update meson rules, the
MAINTAINERS file and all the documentation and comments.

The functions qemu_get_timedate() and qemu_timedate_diff() take
and return a time offset as an integer. Coverity points out that
means that when an RTC device implementation holds an offset
as a time_t, as the m48t59 does, the time_t will get truncated.
(CID 1507157, 1517772).
The functions work with time_t internally, so make them use that type
in their APIs.
Note that this won't help any Y2038 issues where either the device
model itself is keeping the offset in a 32-bit integer, or where the
hardware under emulation has Y2038 or other rollover problems. If we
missed any cases of the former then hopefully Coverity will warn us
about them since after this patch we'd be truncating a time_t in
assignments from qemu_timedate_diff().)

replay_add_blocker() takes an Error *. All callers pass one created
like this:
error_setg(&blocker, QERR_REPLAY_NOT_SUPPORTED, "some feature");
Folding this into replay_add_blocker() simplifies the callers, losing
a bit of generality we haven't needed in more than six years.
Since there are no other uses of macro QERR_REPLAY_NOT_SUPPORTED,
replace the remaining one by its expansion, and drop the macro.

The 'slew' lost tick policy is only available on systems with a mc146818
RTC. On other systems, "-rtc driftfix=slew" is currently silently ignored.
Let's emit at least a warning in this case to make the users aware that
there is something wrong in their command line settings.

softmmu/rtc.c defines two public functions: qemu_get_timedate() and
qemu_timedate_diff(). Currently we keep the prototypes for these in
qemu-common.h, but most files don't need them. Move them to their
own header, a new include/sysemu/rtc.h.
Since the C files using these two functions did not need to include
qemu-common.h for any other reason, we can remove those include lines
when we add the include of the new rtc.h.
The license for the .h file follows that of the softmmu/rtc.c
where both the functions are defined.

Global properties have an @optional field, which allows to apply a given
property to a given type even if one of its subclasses doesn't support
it. This is especially used in the compat code when dealing with the
"disable-modern" and "disable-legacy" properties and the "virtio-pci"
type.
Allow object_register_sugar_prop() to set this field as well.
